Differential cross sections and angle-integrated cross sections of the 6Li(n,t)4He reaction were measured at En = 1.05, 1.54, and 2.25 MeV by using the gridded ionization chamber method. A 6LiF sample and a 238U sample were set back-to-back inside the twin chamber for measurement. Neutrons were produced through the T(p,n)3He reaction. The absolute neutron flux for En = 2.25 MeV was determined by the 238U(n,f) reaction, and those for En = 1.54 MeV and En = 1.05 MeV were determined by a calibrated BF3 long counter. Present results are compared with existing data.
